Has your robot vacuum ever gotten stuck under your Herman Miller Aeron chair? Mine did. Repeatedly. So I made VacStop—a quick-and-dirty solution to keep robo-vacs from disappearing under the chair frame. Pragmatic maker energy. Built by someone who was tired of army-crawling under their desk to rescue a confused vacuum. If you've lived this nightmare, grab the files and print your own. It's not pretty, but it solves the problem
